Key takeaways
  • Whether a renovation needs board approval depends on your declaration, by-laws and rules, not on a single Ontario-wide list.
  • The corporation's insurance does not cover improvements or non-standard parts of a unit, so owners should insure them themselves.
  • Check your documents and get any consent in writing before work begins.

Replacing flooring, moving a wall or redoing a kitchen can be simple in a house. In a condo, even work inside your unit can affect neighbours, the building's structure or the common elements, so many buildings want a say.

This article explains where the answer comes from, what an alterations agreement generally involves, and the insurance points to think about. The exact approvals for your project depend on your building's documents, so confirm them before you start.

The answer is in your governing documents

There is no single list that says flooring needs consent and paint does not. Your building's declaration, by-laws and rules set out which changes need approval. Read all three, and ask management whether the corporation has a standard process or form for owner alterations.

Rules must aim to promote the safety and welfare of owners and property, or to prevent unreasonable interference with the use of units, common elements or assets. They must also be reasonable and consistent with the Condominium Act, the declaration and the by-laws. The declaration is not held to any legal standard of reasonableness, and it is registered, unlike rules, which do not need to be registered.

Which changes usually raise questions

Your documents decide each case, but certain kinds of work tend to draw attention from boards. Knowing them helps you ask the right questions early.

Ask in writing before you hire anyone.

What an alterations agreement involves

Where the corporation allows a change, it often records the terms in a written agreement with the owner. The terms differ between buildings, so read yours carefully. Common subjects include the following.

Have a lawyer review the agreement if it is long, or if it makes you responsible for costs you do not understand.

Insurance and who pays for damage

The condo corporation must insure the units and common elements against major perils such as fire and flood. However, its policy does not cover improvements or non-standard parts of a unit, and fixtures, furnishings, equipment and personal property are not part of a standard unit, so owners should insure them themselves. A renovation that upgrades your unit may therefore sit outside the corporation's policy.

The Condominium Act does not itself make owners carry insurance, but the corporation's governing documents may. Deductibles also matter. Where an owner's own act or omission causes damage, the lesser of the deductible or the repair cost is charged back to that owner's unit. A by-law can make owners liable in more situations, such as accidental damage where no one is at fault. Renovation work that leaks or damages a neighbour's unit could therefore cost you.

What to do next

If you disagree with a rule, owners can ask for a meeting about it by delivering a written requisition that states the topics and is signed by owners of at least 15% of the voting units. Tenants cannot sign a requisition, and neither can owners who are 30 days or more in arrears. When the board proposes a new or changed rule, it takes effect 30 days after notice unless owners requisition a meeting. If they do, the board must hold the meeting and a vote within 35 days, decided by a majority of votes cast by owners.

Frequently asked questions

Do I need board approval to change my flooring?

It depends on your declaration, by-laws and rules. Flooring is a common concern because of sound, so many buildings have specific requirements. Check your documents and ask management in writing.

Can I move or remove a wall in my condo?

Only if your governing documents allow it, and often with the corporation's consent. Walls can affect structure and shared systems, so ask first and get any approval in writing.

Is my renovation covered by the corporation's insurance?

Generally not. The corporation's policy does not cover improvements or non-standard parts of a unit, and owners should insure those themselves.

What if the board says no?

Ask for the reason and the provision it relies on. If the refusal rests on a rule, the rule must be reasonable and consistent with the Condominium Act, the declaration and the by-laws, but the declaration itself is not held to any legal standard of reasonableness, and a pet restriction in it is not subject to the reasonableness test that applies to rules. A lawyer can advise on your options.
